CLEANER AND HULL EXTRACT '01? Filed May 20, 1950 2 Sheets-Sheet 2 Jeffry J Wd/ZEL'E Patented May 19, 193E mean JEFFREY JOHN WALLACE, OIE A1\[ITE, LOUISIANA, ASSIGNOR T GULLETT em COM- PM, OF AMITE, LOUISIANA I (313R AND This invention relates to hulli'ng and cleaning devicesyand more particularly, to hulling and cleaning devices for cotton.

An object of the present invention is to provide a device of the character indicated adapted to continuous operation and calcu lated to easlly and efliciently remove hulls, sticks and other debris from the cotton fiber without injuring the same.

A. further object is to provide a device of the character indicated, with a minimum number of essential parts.

A further object is to provide a device of the character indicatedof an improved and simplified structure and with an improved and novel mode of operation.

Further objects will more particularly appear in the course of the following detaileddescription.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more particularly described in the claims Two sheets of drawings, all of which are largely diagrammatic, accompany this specification as part thereof, in which like reference characters indicate like parts throughout.

provided to support a casing 2 within which are endless belts 3 and 4, ositioned with adjacent reaches parallel an in slightly spaced relationship which adjacent reaches areinclined at an angle to the horizontal.

Endless belt 3, which will be termed the saw-belt, is mounted upon gears 4 and 5 and is constructed with a plurality of outwardly directed'teeth 7 which may conveniently be struck from the body of the belt 8, and which are, as illustrated, of tri-angular shape, having their front. sides 9 perpendicular to the plane of the belt. These teeth are preferably arranged in staggered relationship, but in lines parallel with the travel of the belt.

Belt 4 is provided with outwardy directed spikes 13 arranged to pass between the teeth 7 of belt 3, and isfurther provided with outwardly directed brushes 14 arranged to brush teeth 7. The brushes 14 may be oibristles or 7e wire and may conveniently be mounted in 1 blocks 15 secured as by bolts 17 through angle members 16 and belt 4.

Belt 3 is provided on its inner face with lugs 8 adapted to engage between the teeth of gears 4 and 5 and belt 4 is provided with similar lugs 12, adapted to engage between the teeth of gears 10 and 11 upon which said belt 4 is mounted. At the lower end of belt 3 is positioned a roller 35 provided with outwardly directed prongs 36 adapted to pass between teeth 7. on belt 3 to remove hulls and debris from said belt and below roller 35 is positioned an endless conveyor 37 adapted to receive and remove thedbris from the machine.

Adjacent the upper end of belt 3 is positioned a brush drum 43, having outwardly directed brushes adapted to wipe teeth 7 of roller 3 and these brushes 44 are arranged at an angle to belt 3 so as to wipe teeth 7 on the front advancing the edge rearwardly so as to remove the clean material from said teeth and throw same into chute 48 vthrough which it passes from the machine.

Two feed rollers 18 are positioned above belt 3 and belt 4 adapted to feed the raw material in between these belts at a proper speed,

The belts and varidus rollers are preferably operated from a common source of power,.- W9

30 i particular gears 21 and thus by reason-of the which as illustrated, is shaft 6 upon which is mounted gear 4. Upon the shaft 6 is also mounted a pulley 26, which is connected by 'belt 27 to a pulley 28 mounted on shaft 29 which also carries gear 11 for belt 4. Gear 5, which is driven by: the saw-belt 3 from gear 4, is mounted up'on shaft 30 which also carries a pulley 31 connected by belt 32 to a pulley 33 mounted on shaft 34 which carries the roller 35.

Shaft 6 also carries a pulley 50 which is connected bybelt 46 with a pulley 45 mounted on shaft 44-upon which is mounted brush 43. The feed rollers 18 are operated from shaft 6 by means of a worm 25 on said shaft, which meshes with a gear 24 slidably positioned on a shaft 22 slidably mounted in suitable brackets 23'23. The shaft 22 is provided with a slot 53 to engage a key fitted in gear 24 and also has a key 52 adapted to engage one of a plhrality of gears 21 mounted on shaft 22 and each engaging annularly arranged teeth 51 provided on a disc 20 mounted upon the same shaft with one of the feed .rollers 18,

and these feed rollers are connected by meshed gears 19. A lever39 is pivotally connected to one end of shaft 22 and said lever is pivotally mounted at 40 and provided with a handle 41. By rocking lever 39, the key 52 on shaft 22 can be engaged as desired with radial spacing of said gears on disc 20 the speed of said feed rollers 18 can be varied.

An essential feature of the present invention is the provision for operating saw-belt 3 and gear belt 4 in the same direction, but at V differential speeds, experience indicating that the saw-belt should be advanced atsubstantially twicethe speed as the gear belt. The hull removing roller 35 is rotated in a direction opposite to the direction of travel of the saw-belt and at a peripheral speed substantially the same as that of the saw-belt and the removal brush 43 is also arranged to be rotated in a direction opposite to that of the saw-belt and at substantialy the same speed. By reason of the saw belt and the gear belt travelling in the same direction, but at different speeds, the hulls and dbris are removed from the cotton and the cotton fibers are gently passed over the saw teeth, but without due strain on or breakage of the cotton fibers, such as is encountered, in the preylous known practice of forcing the cleaners 1n a direction. 0 posite to that of the saw, thus thrusting t e cotton through the saw teeth. a I

Various modifications in the precise structure and arrangement of the parts will read- 1ly suggest themselves to those skilled in the art, but all within the scope of the present invention as claimed.

' What I claiin is: 1. cleaner and bull extractin device comprismg in combination an en ess conveyor belt having outwardly directed teeth, an endless conveyorbelt having outwardly directed spikes and brushes, said belts arranged parallel with each other and so that i the spikes will pass-between saw teeth and the brushes will wipe the saw teeth and at i comprising in combination an endless conveyor belt having outwardly directed teeth, an endless conveyor belt having outwardly directed spikes and brushes, said belts arranged parallel with each other. and so that the spikes will pass between the saw teeth and the brushes will wipe the saw teeth and at an inclination to the horizontal, means for feeding material between said belts at the top, means for removing debris at the bottom, means for removing the clean material from the saw .teeth at the top and means for separating said belts from the debris so that the adjacent reaches will travel at a diflerentialspeed, but in the same direction.

3. A cleaner and hull extracting device comprising in combination an endless conveyor belt having outwardly directed teeth, an endless conveyor belt having outwardly directed spikes and .brushes, said belts arranged parallel with each other and so that and'the brushes will wipe the saw teeth and .at an inclination to the horizontal, means theadjacent reaches will travel at a difierential speed but in the same direction, and said brush roller will travelin the direction opposite to that of the saw teeth.

4. A cotton cleaner including a pair of endless conveyor belt'shaving branches parallel to'each other, rows of projections extending from each branch between the rows of the other branch, brushes on one of said branches to contact with and clean the prothe spikes will pass between the saw teeth jections on the other branch, and means for moving said belts to cause said branches to.

move at different speeds in the same direction.

5. A cotton'cleaner including a pair of endless conveyor belts'having branches parlessees ailel to each other, rows of projections extending from each branch between the rows of the other branch, brushes on one of said branches to contact with and clean the projections on the other branch, the projections in each row heingstaggerfi with respect to the projections in the adjacent rows, ami means for moving said belts to cause said branches to move at difierent speeds in the same direction.
